My invention relates to a support for releasably holding a lire extinguishing grenade and is characterized by a hanger, which can be attached to a wall or other structure,

a bracket fusibly connected to the hanger, and

a grenade holder secured to the bracket.

For an understanding of the invention reference is to be had to the following description and to the accompanying drawings, in

which:

Fig. 1 is a front elevation of the support showing the grenade in dotted lines, y

Fig. 2 is a horizontal section on the line A-A, Fig. 1,

Fig. 3 is a vertical section on the line B-B, Fig. 1.

Like characters of reference refer to like parts throughout the speciflcationand drawings.

The container or grenade 1, which may take the form of a fragile bottle or ask of ample storage capacity, is filled with fire extinguishing fluid and held in a suspended position by a support which may be permanently or removably attached to a wall or other suitable structure.

In the construction hereinafter described the support comprises z-a hanger 2, which takes the form of a flat plate provided with flanged edges 3, and has an aperture 4 at or near the top intermediate its lateral sides; a bracket 5, of corresponding shape and dimensions to that art of the hanger which it contacts, provided) with flanges 6 at its lateral and bottom edges for engaging the corresponding flanged edges of the hanger and preventing the upward and sidewise movements of the bracket, independently of the hanger; and a grenade holder 7 secured to the bracket 5.

The grenade holder 7 may consist of any suitable structure capable of holding the grenade, and in the preferred form consists of an infusible wire band or strap, shaped to r conform to, and of sufficient strength and rigidity to support the weight of, the container or grenade. The two ends of this band or strap are bent back upon the body as at 8a and then bent at right angles to its plane to form two arms 8, each of which is entered in a 192s. seriai No. 284,414.

pair of vertically ldisposed and separated sockets `9, Sawhich may be integral with or pressed from the body of the bracket 5 or may be separate from and secured to it by any well known mechanical expedient.

The bracket 5 is formed with an aperture 10 through which is entered a fusible fastener 11 for uniting the bracket to the hanger. This fusible `fastener consists of a metallic alloy which melts at a relatively low tempera- 60 ture, usually but slightly above maximum atmospheric temperature, to permit of the separation of the bracket from the hanger, but otherwise securely fastens the bracket and hanger together and maintains the assembly of the component parts of the support.

v Any type of a fragile container or grenade may beemployed for the fire extinguishing fluid and in the `construction shown it is substantially ovoidal with the'larger diameter of 70 the ovate above the band or strap for the latter to support it from below.

In the use of the apparatus vthe support is attached'at an elevated position, to a wall or other structure. When the temperature of I the lpremises reaches the fusionpoint of the metallic alloy, the fastener melts and permits `the bracket and. hanger to separate and the container Vor grenade to lfall and break for liberating its contents. v

Having Vthus fully describedmy invention, what I claim as new and desire to secure by Letters Patent is: l

1. A grenade support comprising a flat hanger plate for attachment to a supporting structure, a bracket contacting part of the hanger plate, a `fusible fastener entered through `the bracket and hanger plate for securing them together under normal temperature conditions and permitting them to separate when the temperature exceeds a predetermined degree, and an infusible grenade holder connected to the'bracket for embracing the grenade and supporting it from below.

2. A grenade ysupport comprising a flat hanger plate having flanged edges, a bracket contacting part of the hanger plate and of corresponding shape and dimensions to that part of the hanger plate which it contacts, a fusible fastener entered through the bracket m0 and hanger plate for securingthem together under normal temperature conditions and permitting them to separate when the temperature exceeds a predetermined degree,

flanges at the lateral sides of the bracket engaging the corresponding flanged edges of the hanger plate for preventing the Ysidewise movementof the bracket independently Yof the hanger plate and relieving the fusible fastener of lateral strain resulting from such sidewise movement, and anV infusible. grenade holder secured to the bracket for embracing the grenade and supporting it from below.

3. A grenade holder comprising a flat hanger plate provided with flanged edges, a bracket contacting part ofthehanger pl-ate and -of corresponding shape and dimensions to that part lof the hanger plate which it contacts, a fusible-fastener entered through the bracket andhanger plate for securing them together under normal temperature conditions and p/ermittingthem to separate when the temperature exceeds a predetermined degree, flanges at the lateral sides ofthe-bracket engaging the lcorresponding flanged yedges of thehanger plate for preventingthe-sidewise movement off the bracket independently of the hanger plate` and relieving the;fu'sib le fastenerfof lateral strains, resulting from such sidewise movements, and a grenade holder secured to the bracket consisting of an infusible strap shaped to conformu-to ,the grenade Vfor embracing ,it and.. support-ing 4it from below.'v4 v 4.
